WASHER.

SPECIFICATION forming part of Letters Patent No. 760,914, dated May 24, 1904.

Application filed April 13, 1903- 1'0 all whom it may concern/.

Be it known that I, SAM NEWBERRY, a citizen of the United States, residing at Trent, in the county of Taylor and State of Texas, have invented certain new and useful Improvements in Washers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in washers.

The object of the invention is to provide a washer which may be applied to machinery without the necessity of disassembling the same and which will be entirely self-locking.

A further object is to provide an article of this description which is simple in construction and inexpensive of production.

With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claim.

Figure 1 is a plan view of the body member of my two-part washer. Fig. 2 is a similar View of the locking member. Fig. 3 is a plan view of the two parts about to be fitted into locking engagement. Fig. i is a similar view after the parts have been locked. Fig. 5 is an enlarged detail view of a portion of the engaging or looking edges of the members. Fig. 6 is a sectional view through the washer.

Referring to the drawings by numeral, 1 denotes the body member of my improved washer, which is made of spring metal or other suitable resilient material. As shown, this member consists of a ring-shaped disk provided with an open or cut-away portion 2, which is of segmental or wedge shape, or,

in other words, the width of the opening 2 at its inner end, which communicates with the usual central aperture 3 in the washer, is less than the width at its outer end. The width of the inner end of this open or cutaway portion 2 is slightly less than the diameter of the central aperture 3 of the washer. The sides or walls of this opening or cut-away 5 portion 2 are formed with serrations or fine Serial No- 152,420. {No model.)

teeth 4, which are inclined inwardly toward the center of the washer. This construction forms an incomplete annulus having obliquelyinclined spaced end walls, said annulus being resilient to allow said walls to have movement to a restricted extent toward and from each other to contract and expand the opening 2.

5 denotes the wedge-shaped locking member of my two-part washer. The same exactly corresponds in shape and size to the open or cut-away portion 2 of the washer. Its side edges are serrated or provided with fine teeth 6, which are inclined outwardly or toward the broad end of the wedge and which are adapted to engage the teeth 4: upon the body member 1.

When the wedge or looking member 5 is placed in the cut-away portion 2 of the washer, as shown in Fig. 3, a blow of a hammer upon the wedge will cause the latter to spread the obliquely-inclined walls of the resilient body portion sufliciently to permit the wedge to enter said open portion and become locked therein, as seen in Fig. i.

The wedge or looking member 5 forms a segment of somewhat larger size than the metal displaced to form the opening 2 and when inserted within said opening constitutes a complementary member which completes the annular continuity of the body portion.

It will be observed that my improved washer is particularly adapted for use upon shafts and other portions of machinery that become worn by use, and hence have too much play. It may be easily and quickly applied without the necessity of taking the machine apart, and when once in place it will be securely locked by the looking or wedge member 5.

It will be understood that I do not limit myself to the use of teeth, as shown in the drawings, as it is evident that any kind of serrations or locking-surfaces may be employed.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion,

and the minor details of construction may be I resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is-

A washer comprising a resilient metallic body portion consisting of an open-ring disk forming an incomplete annulus, the spaced Walls of such annulus being obliquely inclined in opposite directions, forming a flaring receiving-space and having inwardly-projecting ratchet-teeth, and a segment of Wedge form adapted to fit within said space and expand said walls to place the body portion under tension, said segment being provided with similarly inclined ends formed with outwardly-projecting ratchetteeth adapted to be held in looking engagement with the toothed walls of the body portion by the tension of the body portion, said segment constituting a complementary member completing, when so applied and locked, the annular continuity of the said body portion, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
